    • A rechargeable battery has a battery cell at least partially enclosed by a casing. The battery cell comprises (1) a substrate; (2) a cathode and cathode current collector on the substrate, the cathode being electrically coupled to the cathode current collector; (3) an electrolyte electrically coupled to the cathode or cathode current collector; and (4) a permeable anode current collector having a first surface electrically coupled to the electrolyte and an opposing second surface, the permeable anode current collector: (1) having a thickness that is less than about 1000 Å and that is sufficiently small to allow cathode material to permeate therethrough to form an anode on the opposing second surface of the permeable anode current collector when the battery cell is electrically charged, and (2) that is absent an overlayer on the opposing second surface of the anode current collector. Positive and negative terminals are electrically connected to the battery cell. The permeable anode current collector may be a grid with perforations.
    • 可再充电电池具有至少部分地由壳体封闭的电池单元。 电池单元包括(1)基板; (2)衬底上的阴极和阴极集电器,阴极电耦合到阴极集电器; (3)电耦合到阴极或阴极集电器的电解质; (4)具有电耦合到电解质的第一表面和相对的第二表面的可渗透阳极集电器,所述可渗透阳极集电器:(1)具有小于约的厚度,并且足够小以允许 阴极材料在电池单体充电时,在透气性阳极集电体的相对的第二表面上形成阳极,以及(2)在阳极集电体的相对的第二表面上不存在覆盖层。 正极和负极端子电连接到电池单元。 可渗透的阳极集电器可以是具有穿孔的网格。
